"Trhe` objects of the invention ,arey to prevent tearing 0f the' roofsheets-n Service, to .dol away with holes ,through the roof v.sheets forthe v'securing means, andto provide forthe convenient removal andreplacey mentof worn and-damagedroof sheets, and

to maintain the joints .between the roof sheets tight `Vunder 'Servicekconditions'.

e In.y the drawings, the invention isshown applied to a car having alWooden rooffsubstructure consisting'of roof boards` 11 supridge piece13, bntthesubstructure may be constructedin any manner desired of eitherwood ,or metal. The roof sheets ,14 are ar- `ridge are arranged inalinement'crosswise of the car, and the battens on each side of'the carare in alinement and meet at the ridge.

The ridge ends of the roofsheets are slightly convex, and the middlepoints of the .curved extremities of opposite roof sheets nearly touch,each other at-the ridge lines `midway kThe .sides and ridge endf of eachroof sheet are provided with upstanding flanges 16 withinturnedextremities'17 which vslope down the body portion', of thesheet. The

side Aflanges of ,adjacent roof sheets are covered by sideseamcovers 18,which are supported on the battens 15. These side'seam covers have sidewalls 19 which are turned in at their bottoms. and lthe inturned edges2O of which are hookedunder the extremities 17 of the side flanges ofadjacent roof sheets, as shown iinFig. 3.' This construction provides aloose but watertight connection or joint between the sides of adjacentroof sheets. The invention is-not restricted to this side seamconstruction, and any suiiciently exible searnor joint for connectingvthe roof sheets along their sides may be used.

The eaves ends of the roof ysheets are f i ported at theirends on a sideplatev 12 and strips 23, as shown in Fig. 2. The flashing Strips arenailed or otherwise secured along the eaves of the 'car between thebattens. Angle-shaped eaves clips 24: are secured to the side ofthe carbelow the ends of the roof sheets, withV their top legs projectinginwardly over the eaves ends of the roof sheets 14 and side seam covers18 to holdthem down. The eaves clips are .detachably secured to thefascia board 25 by bolts, and may be quickly removed and replaced whendesired. They rest loosely upon the roof sheets without clampin them, sothe roof sheets are free to move oth lengthwise and crosswise of the carat the eaves. The invention is not restricted to this means of securinthe roof sheets at the eaves, and any sultable method for looselyholding the eaves ends of the roof sheets may be used.

The ridge ends of the roof sheets are covered by ridge seam covers 26which are inverted channel-shape, their side walls 27 having outwardlyextending flangesl 28 which rest on the roof sheets. length the sidewallsp27 of the ridge seam covers are provided with inwardly projectingsemi-cylindrical bosses 29 extending from top to bottom. The twoopposite bosses 29 of each ridge seam cover are adapted to bear againstthe inturned extremities 17" of the ridge end flanges 16 of theunderlying oppositely disposed roof sheets, and thereby the roof sheetsareretained in position on the roof substructure against sliding down.The roof sheets are free to pivot or swing on the bosses 29 and canthereby accommodate themselves to the distortions of the substructurewhich occur in service.

l The ridge ends ofthe side seam covers 18 and the ends of the ridgeseam covers 26 are secured in position by square corner caps 30, theside walls 31 of which arerecessed to fit over the seam covers'. Thesecorner lcaps are bolted to the ridge pole by bolts 32 which also securethe running board saddles 33 in position. The running board saddles reston the side seam covers .18 and battens 15. The running boards 34 may besecured to the saddles in any suitable manner. The weight of the runningboard saddles and running boards is not carried on the roof sheets,`which are freely movable under the side and ridge seam covers withinside walls thereof.

In the modified form of con struction shown in Figs. 6 and 7, the ridgeflanges 35 of the roof sheets 14 are straight insteadof being curved,and the side walls of the ridge seam cover 36 have their lower edgeslturned in and bent up to form trough-shapelanges 37. The inner walls ofthe troughs 37 are curved in so that the troughs are wider at themiddlethan at the ends. The middle pointsof the inside walls of the troughs 37are adapted to `the roof* sheets 1n them to move aroun to accommodatethemselves to thedistortions Midway of their the limits of the contactwith the ridge flanges of the underlying 'op ositely disposed roofsheets and thereby orm a pivotal support or fulcrum on which the roofsheets may bear.

In the modifications shown in Figs. 8 and 9, the ridge flanges 38 of theroof sheets are provided with inturned flanges which are inwardly"curved from their ends to the midline of the roof sheets. The side wallsof the seam ucovers 39 have straight inturned flanges 40 ada ted to bearagainst the middle points of the anges 38, and thereby to retain saidpoints of contact of the substructure in service'.

It is evident that other modifications of the ridge construction can bemade without departing from theinvention, and this invention is notrestricted to any 4one of the arrangements shown and described.

What I claim as my invention and desire to secure by Letters Patent is:

1. A flexible car roof, comprising -roof sheets4 having upstanding4flanges Vat their ridge ends, the Ilan es of adjacent sheets a preachingeach ot er more closely at t e middle than at the corners of the ridgeends of the sheets, ridge seam covers straddling the ridgJlanges ofoppositely arran ed roof sheets, said seam covers having si e wallsadapted to touch said ridge flanges at their middle points only, andmeans for retaining said ridge covers in central alinement on the car.

2. A flexible car roof comprising roof sheets oppositely arrangedon'each side of the rid e and having upstanding flanges at their ri geends, the ridge flanges of opposite roof sheets curving toward eachother at .the middle of their length, said ridge flanges having inturnedtop margins, ridge seam covers straddling the ridge flanges ofoppositely arranged roof sheets, said seam covers having side wallsprovided with pivot bearings for said ridge flanges at their middlepo1nts, and means for retaining said ridge covers on the car, said ridgecovers having outturned flanges along the bases of their sidewalls whichbear upon the roof sheets.

3. A flexible car roof comprising loosely connected roof sheets havinoutwardly curved ridge ends, upstanding a glace while permitting ngesalong said ridge ends, ridge seam covers of inverted channel-shapecovering said flanges, .the side walls of said ridge seam covers havingcylindrical depressions at their middlepoints constituting bossesadapted to bear against the curved ridge `flanges of said roof sheets.

4. A flexible car roof comprising a series of pairs of oppositelydisposed roof sheets extendin from eaves to ridge and loosely connectealong their side margins,l the ridge vends of said roof sheets being'curved out'- bear against said flanges near their middie Wardly. andprovided with marginal anges, points, whereby vsaid roof "sheets 'canpivot 10- the middle points of the roofsheets of each on their midlinesagainst each other and pairbeing loeated inproximity to each other,against said inwardly projecting portions of xsaid `pairs of roofsheets, said ridge seam ridge. seam covers over the ridg'e anges'of theridge seam covers.
